  • containments and odor substances in air introduced into the air purifying apparatus may be decomposed and converted into water and carbon dioxide.
  • the photocatalytic filter 152 may deodorize introduced air by cooperating with the light emitting diodes for photocatalyst 148 .
  • the collection filter 154 performs a function of capturing bacteria in introduced air. To this end, the collection filter 154 may have fine pores such that bacteria do not easily pass through the collection filter 154 .
  • the collection filter 154 may include a filter substance having a folded shape in the flow direction of air as shown in the drawing. Bacteria captured by the collection filter 154 may be sterilized by ultraviolet light emitted from the light emitting diodes for sterilization 146 . The collection filter 154 may increase a time for which bacteria in air are exposed to ultraviolet light for sterilization, thereby enhancing sterilization efficiency of the light emitting diodes for sterilization 146 .
  • the collection filter 154 may be, for example, a known cabin filter. In some embodiments, the collection filter 154 may include germicides. Sterilization efficiency may be further enhanced by the germicides.
  • FIG. 5 is a view schematically illustrating the ultraviolet light emitting diode part according to an embodiment.
  • the ultraviolet light emitting diode part 140 may include a support member 142 on which the light emitting diodes for sterilization 146 and the light emitting diodes for photocatalyst 148 are mounted.
  • the support member 142 may include the openings 144 provided at an outside portion and at a central portion thereof such that air flows through the openings 144 .
  • the support member 142 may be made of a material such as metal having high thermal conductivity.
  • ultraviolet light may be uniformly irradiated toward the first filter part 150 .
  • the ultraviolet light emitting diode part 140 is not limited necessarily to the shown configuration.
  • the ultraviolet light emitting diode part 140 may be arranged in various configurations. That is, if the openings 144 are located such that air may smoothly flow through the openings 144 , the openings 144 may be formed at various positions of the support member 142 .
  • the light emitting diodes for sterilization 146 and the light emitting diodes for photocatalyst 148 may be arranged in various modified configurations.
  • the light emitting diodes for sterilization 146 and the light emitting diodes for photocatalyst 148 may be arranged in a partitioned manner such that a plurality of light emitting diodes for sterilization 146 is present in one region and a plurality of light emitting diodes for photocatalyst 148 is present in the other region.
  • the air purifying apparatus may include the air conduits allowing the air passage to branch.
  • An operation at a low air volume mode for performing sterilization and deodorization functions or an operation at a high air volume mode for performing a sterilization function may be selectively determined.
  • a method of increasing output of an air circulation device such as a circulation fan is adopted in order to increase air volume and air pressure at an air outlet.
  • the present embodiment illustratively describes a case in which the deodorization function is possible during the operation at the high air volume mode, the present disclosure is not limited thereto. If it is satisfied that a differential pressure between the front and rear ends of the second filter part is less than that between the front and rear ends of the first filter part, the second filter part may include various functional filters. In this case, the second filter part may include a filter which may perform the sterilization function. Consequently, the second filter part may perform the sterilization and deodorization functions.
  • the air purifying apparatus may be operated in a state in which the first conduit 120 is opened together with the second conduit 130 .
  • it may be possible to simultaneously and efficiently perform sterilization and deodorization functions and to properly adjust air volume and air pressure, compared to a case in which the first or second conduit 120 or 130 is selectively opened.
  • an operation at a low air volume mode for performing sterilization and deodorization functions or an operation at a high air volume mode for performing a sterilization function may be selectively performed without the aid of a blower fan.
  • the specification may have presented methods and/or processes as particular sequences of steps. However, to the extent that the methods or processes do not rely on the particular order of steps set forth herein, the methods or processes should not be limited to the particular sequences of steps described. As one of ordinary skill in the art would appreciate, other sequences of steps may be possible. Therefore, the particular order of the steps set forth in the specification should not be construed as limitations on the claims. In addition, the claims directed to the methods and/or processes should not be limited to the performance of their steps in the order written, and one skilled in the art can readily appreciate that the sequences may be varied.
